To provide for the lowest possible shelf surface
use the alternate rear vent outlet with attached
ventingroutedinawaytominimizeobstructions
to the use of the space above the appliance. Do
not insulate the space between the appliance
and the area above it. See Figure 9. The mini-
mum height from the base of the appliance to
the underside of combustible materials used to
construct a utility shelf in this fashion is shown
in the Table in Figure 9.
COLD CLIMATE INSULATION
LOCATION
For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside chase cavity between studs and under
floor on which the appliance rests, if floor is
above ground level.
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply
are also important. Consideration should be
given to traffic ways, furniture, draperies, etc.,
due to elevated surface temperatures (see
Figure 4 ). The location should also be free
of electrical, plumbing or other heating/air
conditioning ducting.
Gas line holes and other openings should be
caulked or stuffed with unfaced fiberglass
insulation. If the fireplace is being installed
on a cement slab, in cold climates, a sheet of
plywood or other raised platform can be placed
underneath to prevent conducting cold up into
the room. It also helps to sheetrock inside
surfaces and tape for maximum air tightness
and caulk firestops.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
onornearconventionalconstructionmaterials.
However, if installed on combustible materials,
such as carpeting, vinyl tile, etc., a metal or
woodbarriercoveringtheentirebottomsurface
must be used.
These direct vent appliances are uniquely
suited for installations requiring a utility shelf
positioned directly above the fireplace. Utility
shelveslikethesearecommonlyusedforlocat-
ing television sets and decorative plants. Be
aware that this is a heat producing appliance.
Objects placed above the unit are exposed to
elevated temperatures.

these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 and
-B149.2 in Canada.
The horizontal vent termination must have a minimum of 3" (76 mm) clearance to any overhead
combustible projection of 2 1/2" (64 mm) or less. For projections exceeding 2 1/2" (64 mm), see
Figure 6. All horizontal terminations may be located as close as 6" (152mm) to any combustible
exterior sidewall. This distance may be decreased to 2" (51mm) if the SV4.5HT-2 or SF4.5HT-2
termination is used and the exterior sidewall is non-combustible only. For additional vent location
restrictions refer to Figure 7 on Page 8.

to the nailing flanges, are EXEMPT from the 1/2”
clearance to combustible requirements for the
firebox outer wrapper. Combustible framing may be
in direct contact with the nailing flanges and may
be located closer than 1/2” from screw heads and
the firebox wrapper in areas adjacent to the nailing
flanges. Frame the opening to the exact dimensions
specified in the framing details of this manual.

STEP 2. ROUTING GAS LINE
Remove Cardboard Before
Using Appliance
Route a 1/2" (13 mm) gas line along the inside
of the right side framing as shown in Tables.
Gaslinesmustberouted,constructedandmade
of materials that are in strict accordance with
local codes and regulations. All appliances are
factory-equipped with a flexible gas line con-
nector and 1/2 inch shutoff valve. (See Step 6
on Page 26).
Figure 11
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
TYPICAL INSTALLATION SEQUENCE
Headers may be in direct contact with the
appliance top spacers but must not be sup-
ported by them or notched to fit around them.
All construction above the appliance must be
self supporting. DO NOT use the appliance for
structural support.
The typical sequence of installation follows,
however, each installation is unique resulting
in variations to those described.

• Apipejointcompoundratedforgasshouldbe
used on the threaded joints. Ensure propane
resistant compounds are used in propane
applications. Be very careful that the pipe
compound does not get inside the pipe.
• It is recommended to install a sediment trap
in the supply line as close as possible to the
appliance (see Figure 46). Appliances using
Propane should have a sediment trap at the
base of the tank.
Proper Sizing of Gas Line
Schedule 40 / Black Iron Pipe

Never use galvanized or plastic pipe. Refer to
Table 9 for proper sizing of the gas supply line,
if black iron pipe is being used. Gas lines must
be routed, constructed and made of materials
that are in strict accordance with local codes
and regulations. We recommend that a quali-
fied individual such as a plumber or gas fitter
be hired to correctly size and route the gas
supply line to the appliance. Installing a gas
supplylinefromthefuelsupplytotheappliance
involvesnumerousconsiderationsofmaterials,
protection,sizing,locations,controls,pressure,

andunqualifiedshouldattemptsizingorinstall-
ing gas piping.
• Checkwithlocalbuildingofficialforlocalcode
requirements(i.e.arebelowgradepenetrations
of the gas line allowed, etc).
Table 9
IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insufficient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this, is
not covered under the limited warranty.
Notes:
• All appliances are factory-equipped with a
flexiblegaslineconnectorand1/2inchshutoff
valve (see Figure 46 on Page 26 ).
• See Massachusetts Requirements on Page
4 for additional requirements for installations
in the state of Massachusetts in the USA.
• The gas supply line should Not be connected
to the appliance until Step 6 (Page 26).

orrearflueoutletasshowninFigure17(SSDVR-
3328 ). It is held in place by friction, only.
General Information
A vent restrictor may be needed when horzon-
tally terminating the vent system from the rear
of the appliance (when using the appliance rear
vent), install vent restrictor in the rear vent of
the fireplace outlet on SSDV-3328 series mod-
els, in any installation that has a vertical vent
run in excess of three feet (0.914 meters).
Theseinstructionsshouldbeusedasaguide-
line and do not supersede local codes in any
way. Install vent according to local codes,
these instructions, the current National Fuel
Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 and
-B149.2 in Canada.
Vent Restrictor Installation
(Top Vent)
If needed, install the restrictor orientated as
shown, either from inside or outside the unit,
in the inner fireplace collar
Useonlyapprovedventingcomponents. See
Approved Vent Components on Page 2.
A vent restrictor may be needed when verti-
cally terminating the vent system above the roof
(when using the appliance top vent), install vent
restrictor in the top vent of the fireplace outlet on
SSDV-3328 series models. If needed, install the
restrictor orientated as shown, either from inside
or outside the unit,in the inner fireplace collar.

These fireplaces must be vented directly
to the outside.
Restrictor
The vent system may not service multiple
appliances, and must never be connected to a
flue serving a solid fuel burning appliance. The
vent pipe is tested to be run inside an enclosing
wall (such as a chase). There is no requirement
for inspection openings in the enclosing wall at
any of the joints in the vent pipe.

WARNING
With the appliance secured in framing, de-
termine vent routing and identify the exterior
termination location. The following sections
describe vertical (roof) and horizontal (exterior
wall) vent applications. Refer to the section
relating to your installation. A list of approved
venting components is shown on Pages 32
through 34.
Failure to reinstall and securely
tighten cover plate screws could
result in leakage of flue products
into the living space. Vent cover
plate and vent seal plate must
remain securely installed on
unused vent collar. Failure to do
so could result in leakage of flue
products into living space.

above the roof and/or adjacent walls is speci-
fied in ANSI Z223.1-(latest edition) (In Canada,
the current CAN-1 B149 installation code) by
major building codes. Always consult your lo-
cal codes for specific requirements. A general
guide to follow is the Gas Vent Rule (refer to

usingSecureVent,useSV4.5VFfirestop/spacer
at ceiling joists; when using Secure Flex, use
SF4.5VF firestop/spacer. If there is living space
above the ceiling level, the firestop/spacer
must be installed on the bottom side of the
ceiling. If attic space is above the ceiling, the
firestop/spacermustbeinstalledonthetopside
of the joist. Route the vent sections through the
framed opening and secure the firestop/spacer
with 8d nails or other appropriate fasteners at
each corner. Remember to maintain 1" (25
mm) clearance to combustibles, framing
members, and attic or ceiling insulation
when running vertical chimney sections.
Attic insulation shield (96K94) may be used
to obtain the required clearances indicated
here. See installation accessories, Pages
32 through 34.
Where required, a telescopic vent section
(SV4.5LA) may be used to provide the installer

length pieces develops a joint in a undesirable
location, or will not build up to the required
length. The SV4.5LA Telescopic Vent Section
has an effective length of from 1-1/2" (38 mm)
to 7-1/2" (191 mm). The SV4.5LA is fitted with
a locking inclined channel end (identical to a

K. Install the vertical termination - The final
step involves installation of the SV4.5CGV-1
Vertical Termination. Extend the vent sections
to the height as shown in the "Vertical vent ter-
mination section" on Page 7. The SV4.5CGV-1
VerticalTermination(Figure25)canbeinstalled
in the exact same fashion as any other Secure
Vent section. Align the termination over the
end of the previously installed section, adjust-
ing the radial alignment until the four locking
dimples of the termination are aligned with
the inlets of the four incline channels of the
last vent section. Push the termination down
until it fully engages, then twist the termination
clockwise running the dimples down and along
the incline channels until they are seated at the
end of the channels.
One method of support is by utilizing field pro-
vided support straps (conventional plumber's
tape). Securetheplumber'stapetotheframing

F.Changeventdirectiontohorizontal/inclined
run - At transition from or to a horizontal/in-
clined run, install the SV4.5E45 and SV4.5E90
elbows in the same manner as the straight vent
sections. The elbows feature a twist section to
allow them to be routed about the center axis
of their initial collar section to align with the
required direction of the next vent run element.
Twist elbow sections in a clockwise direction
only so as to avoid the possiblity of unlocking

Horizontal terminations have been designed to perform in a wide range of
weather conditions. Our terminations meet or exceed industry standards.
IMPORTANT
When selecting the locations of your horizontal terminations, do not place the
termination where water from eaves and adjoining rooflines may create a heavy
flow of cascading water onto the termination cap. If the cap must be placed
where the possibility of cascading water exists, it is the responsibility of the
builder to direct the water away from the termination cap by using gutters or
other means.
The vent termination is hot while
in operation and for a period of
time following the use of the fire-
place. To prevent contact with hot
surfaces, we recommend the use
of a Termination Guard. See Items
12 and 13 on Page 32. This can be
purchased at your local dealer.
Take care to carefully follow the installation instructions for the termination,
including the use of silicone caulking where required.

Never use an open flame to
check for leaks.
To light the burner; rotate the gas valve control
knob counterclockwise to the “ON” position
then turn “ON” the OFF/ON switch (installed
at Step 4).
Reinstalling Control Compartment Door:
To reinstall, insert the hook catches on each
side of the door into the corresponding slots
in the control compartment opening, then
gently push forward and slide down until it
locks in place.
Turn on gas supply and test for gas leaks using a
gas leak test solution (also referred to as bubble
leaksolution). Note:Usingasoapywatersolution
(50% dish soap, 50% water) is an effective leak
test solution but it is not recommended, because
the soap residue that is left on the pipes/fittings
can result in corrosion over time.
Observe the individual tongues of flame on
the burner. Make sure all ports are open and
producing flame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.

Installing Glass Enclosure Panels
Air Shutter Adjustment Guidelines
Step 9. INSTALLING THE GLASS DOOR
(see Figure 54)
• If there is smoke or soot present, first check
the log set positioning to ensure that the
flames are not impinging on any of the logs.
If the log set is properly positioned and a
sooting condition still exists, then the air
shutter opening should be increased.
• Themoreoffsetsintheventsystem,thelarger
the air shutter opening will need to be.
• An appliance operated with the air shutter
openedtoofar, mayhaveflamesthatappear
blue and transparent. These weak, blue and
transparent flames are termed anemic.
• Propane models may exhibit flames which
candle or appear stringy. If this is present
and persists, adjust the air shutter to a more
closed position, then operate the appliance
for a few more minutes to ensure that the
flame normalizes and the flames do not
appear sooty.

blueatthebaseandbecomesyellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
graduallyturnyellowish-orangeduringthefirst
15 minutes of operation. If after a short period
the flame stays lowered blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.
Do not attempt to touch the front
enclosure glass with your hands
